Understanding security warnings
If audit logs checks fail, it is possible that
your ISDN gateway has been
compromised. For example, someone
may have taken the compact flash card
out and deleted some audit logs.
For more information on the audit log,
refer to Working with the audit
If no compact flash card is installed in the
ISDN gateway, logs are only stored up to
a maximum of 200 events. The 200
events do not 'wrap', and therefore when
the maximum is reached the log is
deleted and started over again.
The ISDN gateway will give you this
warning when you are nearing the 200
maximum. To rectify this problem, insert a
compact flash card.
When encryption status is Disabled, no
calls on the ISDN gateway will be able to
use encryption.
To enable encryption, go to Settings >
Encryption. For Encryption status, select
Enabled.
The audit log has a maximum capacity of
200,000 audit events, or the size limit of
the compact flash card. When you are
nearing either of these limits, the ISDN
gateway will give you this warning. To
rectify this problem download and clear
the audit log.
To do this, go to Logs > Audit log and
select Download as XML. Once this has
completed, click Delete all records.
